A model for diffusion and phase separation which takes into account relaxation of the solute diffusion flux is developed. It is shown that the model predicts non-linearity in the amplification rate of decomposition, which is governed by the ratio between diffusion and correlation lengths. The predicted amplification rate is tested against experimental data on a binary phase-separated glass.
Supersymmetry theory of diffusion is elaborated to study analytically a non-equilibrium binary mixture with relaxation of diffusion flux. Within such a scheme, Bose components represent order parameter and amplitude of fluctuations of the diffusion flux, while the mutually conjugated combination of Fermi-components gives the mixture concentration. For above variables, the system of equations is found...
